Covering both theoretical and practical interest in different networks layers, multicast routing remains an important topic. In network layer, there are several multicast routing protocols using different multicast routing trees in the literature. However PIM-SM and CBT protocols remains the most used multicast routing protocols; they propose using a shared tree (ST). This kind of tree provides efficient...
Delay tolerant networks (DTNs) are a class of emerging networks that experience frequent and long-duration partitions. Multicast supports the distribution of data to a group of users, a service needed for many potential DTN applications, due to the unique characteristic of frequent partitioning in DTNs, multicasting in DTNs is a considerably different and challenging problem. In this paper, The mathematics...
The main character of Delay Tolerant Networks (DTNs) is that there is not an end-to-end path from the source node to the destinations due to the intermittent connections and mobility of nodes. In this paper, we construct the mathematic model based on queue with vacation theory to analyze the impact of buffer management strategy on DTN multicast routing, and then compute the minimal delay and maximal...
Two classic categories of models exist for computer networks: network information flow and network of queues. The network information flow model appropriately captures the multi-hop flow routing nature in general network topologies, as well as encodable and replicable properties of information flows. However, it assumes nodes in the network to be infinitely powerful and therefore does not accurately...
